LOOSE-LEAF BINDER.

Specication of Letters Patent.

Application led .Tuly 17, 1917. Serial No. 181,063.

To all 'whom t may concern.'

Be it known that I, JOHN SCHADE, a citizen of the United States,residing at Holyoke, Hampden county. State of Massachusetts, haveinvented certain new and useful lmprovements in Loose-Leaf Binders; andI do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to certain new and useful improvements in a looseleaf binder and more particularly to a sheet holder especially adaptedfor use on a desk for holding loose leaves which are inserted thereinfrom time to time.

The primary object of this invention resides in a novel and peculiarhinge construction between the cover and base sections of the binderwhich will be neat and attractive in appearance and capable of anexpeditious.-

assemblage.

A further and important object is found in the mounting of a spring inthe hinge, and the particular cooperation between the two.,

Other objects will appear as the description progresses and thosefeatures on which protection is desired will be succinctly set fortn 1nthe appended claims, Lreference being had to the accompanying drawingwherein,

Figure l is a top plan view of a loose leaf binder embodying the presentinvention;

Fig. 2 is an end elevation of the hinge portion thereof; and

Fig. 3 is a fragmentary section on line 3-3 of Fig. 2..

Referring in detail to the drawing, the binder here depicted comprises abasev section l, a cover section 2, and a clamping section 3, the twolatter sections having complemental hinge knuckles Llthat register toreceive the hinge pivotal connection therebetween. Y

The rear edge of the base section is eX- tended upwardly at right anglesand thence outwardly, the same being rolled into scroll form to providea hinge pin or shaft 6. rlhe rear edge of the clamping section 3 is alsorolled into scroll form about the inner hinge section 6 to provide anouterhnge pin 5 for constituting a 'from the base "section section 7which is freely rotatable to a limited extent about said inner hingesection.

Arranged in each end of this scroll hinge is a coil spring 8 which hasits inner end passing outwardly beneath the free edge of the scrollsection 6 for bearing against the upturned rear edge portion of thebase, as depicted in Fig. 2. The opposite or outer end of each spring ispassed through registering end notches 9, formed in the end edges of theinner and outer hinge sections, and given a hook bend l0 which seats onthe outer face of the clamping section., The free edge of the outerscroll section 'l is preferably formed with spaced recesses 1l in whichthe inner spring terminals are-received on opening the clamp section.

ln operation, the cover section is swung backwardly on tothe clampingsection and by resting one hand on the base section and pressing down onthe free edge of the cover section with the section will be swung awayfrom the base section on the scroll hinge until limited by the innerspring terminals engaging in the notches 1l as well as the outer springterminals being abutted by opposing walls ofthe registering notches 9.The loose leaves may then be readily inserted in the gap between theclamping and base sections.

This particular construction of hinge leaves the outer face of the topperfectly plain and attractive in appearance, the inner section beingeasily removed through a telescopic action. The disposition of thesprings in the ends of the scroll hinge renders the constructionexceedingly simple, each end bearing on va respective section to affordthe proper resiliency and one terminal at least constituting a' stop todetermine the opening movement tion.

at is claimed is: 1. ln a loose leaf binder, a base section having itsrear edge portion turned upwardly and thence outwardly and rolled intoscroll form, the free edge of the rolled part being spaced from theremaining portion, a clamping section havin one edge portion also rolledinto scroll fo about the scroll part of the base section for relaotherhand the clamping f Patented May 2l, ll.
